World's Most Wanted: Who's Left on the List?

The world's most-wanted list has lost two of its most prominent members in the past month. U.S. Navy SEALs killed Osama bin Laden May 1 in Abbottabad, Pakistan, and officials today arrested the Bosnian Serb general, Ratko Mladic, who is suspected of massacring 8,000 Muslim men and boys, in Lazarevo, Serbia.

Here's a look at who's left on the list:
